Q: My 48 years old father is having glaucoma for the last 6 years. The doctor advised an eye operation and we got it done. But even after the operation, my father kept on losing his vision and at present he has only 10% vision in left eye and almost 2% in the right eye. Please advise.

A:Glaucoma being a progressive disease, requires close and continuous monitoring while treatment continues in the form of drops and/or operation as required. The patient may require additional treatment (over and above the Glaucomol drops being used) if his condition is continuing to progress and he is not maintaining target pressure. A review with the glaucoma specialist, field testing, optical coherence tomography (OCT), etc. may be required before any changes are made.
